LOS ANGELES – Summer is drawing to a close, but a midsummer heat wave hits Southern California on Wednesday that will last until Thursday before a cooling trend begins.
A heat warning from the National Weather Service is in place in the San Fernando Valley through 8 p.m. Wednesday, with temperatures of up to 105 degrees expected. According to the NWS, there will also be unusually warm weather in other valley areas, with temperatures around 10 degrees above normal.
“The warm and dry weather will last until Wednesday, with temperatures well into the 90s to below 100s in the hottest inland valleys,” said the NWS.
Inland Orange County areas including Santa Ana, Anaheim, Garden Grove, and Fullerton will be under heat counseling from 10 a.m. to 8 p.m. Wednesday.
Tuesday’s hot weather toppled some local records. Long Beach peaked at 98 degrees, breaking the 97-degree record set on the same day in 1989. Sandberg hit the 2011 record of 90 degrees. In Orange County, Anaheim hit 104 degrees on Tuesday, breaking the 2015 record of 102 degrees.
Conditions should change starting Thursday, with a return of onshore river and the arrival of a low pressure system likely to cool temperatures by Sunday. Forecasters said there could be afternoon thunderstorms in the mountains and desert on Friday and Saturday.
As usual, forecasters warned local residents to take precautions when out in the heat, such as drinking plenty of fluids, avoiding prolonged exposure to the sun, and looking for vulnerable relatives and neighbors.
